-LRB- CNN -RRB- -- It started out as a lovely summer night in northern California : an outdoor concert at a winery that 's set among redwoods and that bills itself as `` miles away but worlds apart . ''

But Thursday 's show by the band The Swell Season at the Mountain Winery , just outside San Jose , turned tragic when a concertgoer leapt from the roof of the stage , landed near the lead singer and died , in what authorities say was a suicide .

`` Upon arriving , deputies found a doctor and an EMT on the scene , performing CPR on the victim , '' said Rick Sung , public information officer for the Santa Clara County Sheriff 's Office . `` They did that for almost half an hour when the doctor pronounced the victim dead . ''

The suicide victim , Michael Edward Pickels , 32 , had attended the concert with a friend , Sung said .

`` During the performance , the victim left his personal items behind with his friend , '' Sung said .

`` The next thing -LRB- witnesses -RRB- see is the victim appears on the rooftop out of nowhere and throws himself off . ''

The roof was about 35 to 40 feet above the stage , Sung said . The doctor who pronounced Pickels dead had been attending the concert .

Authorities said Saturday that Pickels had been out of jail on $ 150,000 bail after threatening to kill his girlfriend and himself on New Year 's Day . Pickels had been charged with assault with a firearm , domestic violence and false imprisonment , Sung said .

Pickels had bound his girlfriend , aimed a loaded gun at her , and said he was going to kill them both , according to Sung . The girlfriend talked him out of it , Sung said , then fled and phoned the sheriff 's office .

When deputies arrived at Pickels ' house , he refused to come out for 90 minutes before surrendering .

Pickels ' death was ruled a suicide by Santa Clara County 's coroner Friday , Sung said .

The Mountain Winery relies on Santa Clara County sheriff 's deputies to patrol its parking lot and concessions area during concerts , Sung said , but provides its own security for the stage and audience area .

The winery , located in Saratoga , did not immediately return a call for comment Saturday night , though it addressed the incident in a brief message on its web site .

`` Thank you to all of you -LSB- who -RSB- have inquired about the unfortunate incident that occurred here on Thursday evening , '' the message said . `` While we are working with local authorities in investigating this incident , there will be no changes to our concert schedule . ''

The Swell Season , a pop/rock duo , has reflected on the incident on its web site and social networking sites .

`` The band , crew and all involved with them are shocked and saddened by the death that occurred at last night 's show , '' the songwriting duo said on its Twitter page Friday .

The Swell Season posted another message on its Facebook page Saturday before a concert in Washington state .

`` Making and performing music is what the band has always done in good times and in bad , '' it read . `` Our hope is that in this communal experience tonight we can somehow help our own grieving process after what we just witnessed . The show will most certainly be different than any other we have ever played . ''

`` We wish to continue to be sensitive to family and friends of this individual and hope that in performing it is not viewed as a selfish act , '' the message continues . `` We have not come to this decision lightly . We continue to have them at the forefront of our minds and hearts . ? ''
